I am sending a couple of commands as part of a .run file to communicate with a device. However, the commands need some delay in between, which cannot be added, as the chip commands do not have a delay.
I am looking for a way to avoid sending one command at a time as a.run file.

To insert a delay between system commands, use the MATLAB pause command which will delay execution by n seconds as shown below:
system('dir')
pause(1)
system('dir')

The question turns out to be about creating a data file for file redirection like
system("Program.exe < thedatafile")
but the poster wanted some mechanism to be able to mark delays about when individual lines of the file data was made available to the program, all within the same system() call.
This is not possible.
Some operating systems support piping the output of processes, so a program could be written which interpreted a marked-up data file, sending the lines to output and pausing appropriately.
For example one could create a ksh / bash script such as
print "First command here"
sleep 3
print "second line"
print "third line"
sleep 20
print "4th line"
and then
system('TheScript | Program')
I do not know the MS Windows equivalent
